Powerful Audio Tools — Right in Your Browser

Everything you need to edit, enhance, and export professional audio. No downloads, no accounts, no limits.

AI Noise Reduction

Remove background hiss, hum, and fan noise with one click. Our TensorFlow powered spectral analysis learns the noise profile from your recording and removes it intelligently — all without uploading your file.

Trim, Cut & Split

Select any region on the waveform and trim to keep just that section, cut to remove it, or split your audio into separate clips. Precise editing with visual zoom up to 600 px/s for frame-accurate results.

Voice Effects & Filters

Apply 11 real-time voice effects including Chipmunk, Monster, Robot, Echo, Reverb, and Chorus. Preview any effect instantly during playback and control intensity with a single slider before exporting.

Studio Enhance

One-click professional audio enhancement that applies dynamics compression, a high-shelf "air" boost, and normalization. Makes dialog, podcasts, and voiceovers sound polished and broadcast-ready.

Drag & Drop Import

Simply drag any audio file onto the editor — MP3, WAV, M4A, AAC, OGG, OPUS, FLAC, WEBM, and AIFF are all supported. The waveform appears instantly and you can start editing right away.

Fast WAV & MP3 Export

Export your finished audio as lossless WAV or compressed MP3 with all effects baked in. Embed custom ID3 metadata — title, artist, album, year, genre, and album art — directly into your exported file.

How It Works

Three simple steps from raw recording to polished audio — no software installation needed.

1

Import Your Audio

Drag and drop any audio file directly into the editor, or click the Import button to browse your files. Your audio loads instantly with a visual waveform so you can see every detail of the sound.

2

Edit & Enhance

Select regions on the waveform to trim, cut, or split. Apply voice effects, adjust playback speed, boost volume up to 400%, or use AI Noise Reduction to clean up background noise automatically.

3

Export & Share

When you are happy with your edits, export as WAV for maximum quality or MP3 for compact file size. All your effects, speed changes, and volume adjustments are baked into the final download.

Frequently Asked Questions

Quick answers to the most common questions about editing audio online.

Is OnlineAudioEdit really free?

Yes, 100% free. There are no trials, no premium tiers, no watermarks, and no file size limits. Every feature — including AI Noise Reduction, 11 voice effects, Studio Enhance, metadata editing, and WAV/MP3 export — is available to all users at no cost.

Do my audio files get uploaded to a server?

No. Your audio files never leave your device. All editing, effects processing, and even AI Noise Reduction run entirely inside your web browser using the Web Audio API and TensorFlow.js. We have no servers that receive, store, or process your audio. Your recordings remain completely private.

What audio formats are supported?

OnlineAudioEdit supports importing MP3, WAV, M4A, AAC, OGG, OPUS, FLAC, WEBM, and AIFF files — essentially any format your browser can decode. For export, you can save your finished audio as WAV (lossless quality) or MP3 (smaller file size). A "Match import" option tries to match your original format automatically.

How does AI Noise Reduction work?

Our AI Noise Reduction uses TensorFlow.js to perform spectral gating directly in your browser. It learns a "noise profile" from either the first half-second of your recording (auto-detect) or a region you manually select. Then it removes that specific noise pattern — like air conditioner hum, fan buzz, or microphone hiss — while preserving voices, music, and the sounds you want to keep.

Can I use this on my phone or tablet?

Yes. OnlineAudioEdit is fully responsive and works on any modern mobile browser including Chrome, Safari, Firefox, and Edge. The interface automatically adapts with a slide-out sidebar and touch-friendly controls so you can edit audio comfortably on smaller screens.

What is the difference between Trim, Cut, and Split?

Trim keeps only the selected region and removes everything else — perfect for extracting a highlight clip. Cut removes the selected region and joins the remaining parts seamlessly — great for deleting mistakes or awkward pauses. Split divides your audio into separate clips at the selection boundaries so you can work with each part independently.
